Downy mildew causes rapid and severe foliar losses in D. tenuifolia. The existence of pathotype diversity hinders resistance breeding. This study identified H. diplotaxidis pathotypes and analysed their phylogenetic relationships. ABSTRACT Downy mildew (DM) caused by the oomycete Hyaloperonospora diplotaxidis (=Peronospora diplotaxidis) is a ...

Extracts of Hormophysa triquetra showed antifungal activity with marked hyphal deformities in Fusarium oxysporum and Alternaria alternata. Light microscopy and SEM confirmed structural alterations despite unchanged radial growth. Cucumber assays validated reduced disease incidence, linked to fatty‐acid–rich metabolites detected by GC–MS.

Soil fungal communities associated with Araucaria araucana differ primarily according to site edaphic conditions rather than tree health status. Restrictive, nutrient‐poor soils are linked to higher canopy dieback and distinct functional community shifts, with symptomatic trees harbouring stress‐tolerant taxa and asymptomatic trees supporting ...

Exotic Plant Pathogen Reduces Habitat and Foraging Activities of a Digging Mammal
The invasive plant pathogen Phytophthora cinnamomi causes extensive damage to Australian ecosystems and likely degrades the habitats of many animals. This study investigated the impact of P. cinnamomi invasion on habitat and foraging of a bandicoot species.

Comparative Performance of Fungicides in Management of Phytophthora Root Rot on Boxwood
Nursery growers rely on fungicides to manage root rot disease of boxwood caused by Phytophthora nicotianae and P. cinnamomi. Repeated use of the same fungicide may lead to the fungicide resistance.

Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...

ABSTRACT Invasive tree pathogens pose a significant and increasing threat to natural ecosystems. The outcome of these novel host‐pathogen interactions depends largely on the presence and nature of resistance in host populations, which will govern the host's potential to respond through natural selection and adaptation to the new threat.

Émergence des Phytophthoras forestiers
Les espèces de Phytophthora (oomycètes, straménopiles) occupent une position de premier plan parmi les agents phytopathogènes émergents en forêt. Dans cet article, trois exemples concrets seront présentés, à savoir le déclin du maquis en Sardaigne dû à l’
